Speaking with Shana correspondent, he added that normally all the oil and gas fields, including the South Pars gas field, experience declining output after several years of withdrawal which requires taking initiatives to prevent falling productivity.  

He continued: Based on its research and studies, the South Pars Oil and Gas Company has decided to drill 35 new wells at different phases of the giant gas field as the first step to stop declining natural gas production.   

These drillings will be carried out on 17 existing platforms of the gas field by four domestic companies including Petro Pars, Petroiran Development Company, North Drilling Company, and Pasargad Energy Development Company. Except for Petro Pars, which plans to drill 8 wells, each of the three other companies will drill 9 wells.  

The cost of drilling is estimated at 1.2 billion dollars, he said.
